'IMPROV EMENT IN MACHINES FORCUTTING CORKS.

Specification forming part of Letters Patent No. 199,047, dated January 8, 1878; application filed November 23, 1877.

To all whom it may concern:

Be itknown that-I, ANTONIO FABRE, of the city, county, and State of New York, have invented'a new and useful-Improvement in Cork-Cutting Machines, which invention is fully set forth in the following specification, reference being had to the accompanying drawings, in which- Figural represents aside elevation of amachine constructed according to my invention.a Fig. 2 is a plan or top view thereof. Fig. 31s a cross-section in theplane of the line w m, Fig. 1. Fig. 4 is a like section in the plane of the line y y, Fig. 1.

Similar letters indicate corresponding parts.

My improvementrelates to machines for cutting-or shaping corkfor bottle-stoppers; and it-consists in the combination of a bedplate, a knife-receiving socket in'said bedplate, a knifeguide located above the bedplate, and a blank-cutting knife moving on said guide, and projecting into said receivingsocket, in such manner that, if a strip of cork is placed on the bed-plate transversely to said knife, the same can readily be cut into blanks of suitable form to be finished or shaped into bottle-stoppers; also, in combining with the parts above enumerated an adjustable gage, for regulating the size of the blanks into which the cork is cut by said blank-cutting knife; also, in the combination, with a clutch-shaft, of a hinged finishing-knife, reciprocating on a guide made adjustable relatively to the clutchshaft, so that a tapering form is given to a cork or stopper operated upon by the knife.

In the drawings, the letter A designates the bed-plate of my machine, in which is formed a knife-receiving socket, b, Fig. 4, and B is a knife-guide, having the form of a rod, whichis located above the bed-plate A, and supported by standards a a. O is the blade of the blank-cutting knife, preferably made with an oblique cutting-edge, and which is secured to a stock, d, embracing the guide B, so as to move or slide thereon, and having a handle, 0.

A strip of cork of a width equal to the length of the bottle-stoppers to be produced, and of a thickness equal to the diameter thereof, is placed on the bed-plate A, transversely to the blade 0 of the blank-cutting knife, and

use of a gage or stop, D, which serves to an rest the cork as it is fed or moved forward, as stated. This gage D is made adjustable, so

as to permit of regulating the size of the cork-- blanks, and in the'example shown it is attached toa bar, d, projecting from the blade 0 of the blank-cutting knife, so that the gage is caused to move with said knife. Said gage, moreover, is attached to the bar d by means of an adjusting-screw, e.

p The letter E designates the two sections of a clutch secured to the inner ends of a divided shaft, F, which has its bearings in standards Gr, rising from the bed-plate A, and to the outer ends of which are secured cog-wheels ff. Adj acent to the clutch-shaft F is located a guide, H, for the finishing-knife I, this guide, like the knife-guide B, having the form of a rod, which is supported by standards 9 g. The blade of the finishing-knife I is secured to a stock, h, which embraces the guide H, so as to move or slide thereon, and is supported in a horizontal position, or nearly so, by a rest or bracket, J, (see Fig. 3,) this knife-stock being, moreover, provided with a handle, i.

The letter K designates a driving-shaft, having its bearings in standards jj, and provided with cog-wheels k k, which mesh with the cogwheels f f of the clutch-shaft, so that the latter partakes of the motion of said driving shaft. The driving-shaft K connects with the stock it of the finishing-knife in such way that when the latter is moved forward a revolving motion is imparted to said shaft.

In the example shown this object is eifected by connecting to the stock h of the finishingknife one end of a cord or chain, Z, which is wound on a pulley, m, secured on the drivingshaft K, and to the other end of which is fastened a weight, it, said cord being guided on the pulley m by a wheel, 0. (See Fig. 2.) When the knife-stock h is moved forward the cord or chain 1 is unwound from the pulley m at one end, and wound thereon at its other end, whereby said pulley, and with it the driving-shaft K, is caused to revolve. knife-stock is moved back to the position shown, the cord or chain Z is returned to its normal position by the action of the weight 'n.

The cork-blank to be finished is held or clamped in the clutch E, the parts of which have a tendency to move toward each other, one section of the clutch-shaft F being subjeeted to the action of a spring, 10, for this purpose, while to the same section of said shaft is connected a rope or chain, g, by which it can be drawn back against the action of said spring, so as to release the cork-blank. The rope or chain q passes over one or more wheels,

' r, and is connected to a treadle, L.

When the cork-blank has been fastened in the clutch E, the finishing-knife is moved forward by taking hold of the handle 6, the same being allowed to lie on its rest J during this movement, when such blank is revolved by reason of the revolution of the clutch-shaft F and clutch, while at the same time the blank comes in contact with the blade of the finishing-knife I, and is thereby cut or shaped to the form of a bottle-stopper.

The position of the knife-rest J determines the diameter of the stopper produced by the When said that one or the other thereof can be inclined, which has the efl'ect of giving to the stopper a tapering form.

In the example shown both said clutchshaft F and the knifeguide H are adjustable, and the method of accomplishing this object consists in securing the standards G g g, which support said shaft and guide, to the bed-plate A by means of screw-bolts s, as shown.

What I claim as new, and desire to secure by Letters Patent, is

1. In a cork-cutting machine, the combination of a bed-plate, a knife-receiving socket in said bed-plate, a knife-guide located above the bed-plate, and a blank-cutting knife mov ing on said guide and projecting intothe receiving-socket, substantially as described.

2. The combination, in a cork-cutting machine, of an adjustable gage for regulating the size of the corkblank with a bed-plate, a knife -receiving socket in said bed plate, a knife-guide located above the bed-plate, and a blank-cutting knife moving on said guide and projecting into the receiving-socket, substantially as described.

3. The combination, in a cork-cuttin g machine, of a clutch-shaft and a hinged finishingknife, reciprocating on a guide made adjustable with relation to the clutch, substantially as and for the purpose set forth.

In testimony whereof I have hereunto set my hand this 16th day of November, 1877.
